After a tenure of just over eight months, Brent Rafferty, chief executive officer of the Kenosha Community Health Center, has resigned.

Rafferty cited personal reasons for his departure, according to a news release issued Tuesday by KCHC board of directors President Joe Clark.

Alan Marshall, KCHC’s chief operating officer, has assumed the role as interim CEO.

Marshall has been the center’s chief operating officer since July 2016. Previously, he worked with Family Health Center of Marshfield Inc., a large federally qualified community health center.

Rafferty assumed leadership of the KCHC on Aug. 1, 2017.
